Philadelphia, February 22, 2021--In April 2020, pediatricians began recognizing a puzzling syndrome in children involving hyperinflammation that results in an array of symptoms, including fever, gastrointestinal distress and rash. The syndrome, thought to be a post-infectious complication of SARS-CoV-2 infection, was given the name Multisystem Inflammatory Syndrome Children, or MIS-C. However, diagnosing the condition has posed challenges, as many of its symptoms, including rash, are common in many other pediatric infections.
It has long been known that several chemicals used in plastic toys in different parts of the world can be harmful to human health. However, it is difficult for parents to figure out how to avoid plastic toys containing chemicals that may cause possible health risks to their children.
About 70% of the world's main crops depend on insect pollination. Climate change is already affecting the abundance and distribution of insects, which could cause geographical mismatches between crops and their pollinators. Crops that rely primarily on wild pollinators (e.g., crops that cannot be effectively pollinated by commercial colonies of honey bees) could be particularly in jeopardy. However, limited information on plant-pollinator associations and pollinator distributions complicate the assessment of climate change impacts on specific crops.
The team of Professor Dongling Ma of the Institut national de la recherche scientifique (INRS) developed a new approach for foldable and solid devices.
COLUMBUS, Ohio - Fool the novel coronavirus once and it can't cause infection of cells, new research suggests.
Scientists have developed protein fragments - called peptides - that fit snugly into a groove on the SARS-CoV-2 Spike protein that it would normally use to access a host cell. These peptides effectively trick the virus into "shaking hands" with a replica rather than with the actual protein on a cell's surface that lets the virus in.
Intravenous injection of bone marrow derived stem cells (MSCs) in patients with spinal cord injuries led to significant improvement in motor functions, researchers from Yale University and Japan report Feb. 18 in the Journal of Clinical Neurology and Neurosurgery.
For more than half of the patients, substantial improvements in key functions -- such as ability to walk, or to use their hands -- were observed within weeks of stem cell injection, the researchers report. No substantial side effects were reported.
ITHACA, N.Y. - In the same way that Lego pieces can be arranged in new ways to build a variety of structures, genetic elements can be mixed and matched to create new genes, according to new research.
A long-proposed mechanism for creating genes, called exon shuffling, works by shuffling functional blocks of DNA sequences into new genes that express proteins.
ITHACA, N.Y. - A new study identifies a mechanism that makes bacteria tolerant to penicillin and related antibiotics, findings that could lead to new therapies that boost the effectiveness of these treatments.
Antibiotic tolerance is the ability of bacteria to survive exposure to antibiotics, in contrast to antibiotic resistance, when bacteria actually grow in the presence of antibiotics. Tolerant bacteria can lead to infections that persist after treatment and may develop into resistance over time.
COLUMBIA, Mo. -- When teachers encounter disruptive or noncompliant students in the classroom, they typically respond by focusing on the negative behavior. However, new research from the University of Missouri found that offering students more positive encouragement not only reduces disruptive classroom behavior, but can improve students' academic and social outcomes.
When you slip into sleep, it's easy to imagine that your brain shuts down, but University of Michigan research suggests that groups of neurons activated during prior learning keep humming, tattooing memories into your brain.
Abu Dhabi, UAE, February 22, 2021: Learning more about what motivates people to join violent ideological groups and engage in acts of cruelty against others is of great social and societal importance. New research from Assistant Professor of Psychology at NYUAD Jocelyn Bélanger explores the idea of ideological obsession as a form of addictive behavior that is central to understanding why people ultimately engage in ideological violence, and how best to help them break this addiction.
Establishing a consistent sleep schedule for a toddler can be one of the most challenging aspects of child rearing, but it also may be one of the most important.
Research findings from a team including Lauren Covington, an assistant professor in the University of Delaware School of Nursing, suggest that children with inconsistent sleep schedules have higher body mass index (BMI) percentiles. Their findings, published in the Annals of Behavioral Medicine, suggest sleep could help explain the association between household poverty and BMI.
LOGAN, UTAH, USA -- You might not like mosquitoes, but they like you, says Utah State University biologist Norah Saarman. And where you lead, they will follow.
In addition to annoying bites and buzzing, some mosquitoes carry harmful diseases. Aedes aegypti, the so-called Yellow Fever mosquito and the subject of a recent study by Saarman and colleagues, is the primary vector for transmission of viruses causing dengue fever, chikungunya and Zika, as well as yellow fever, in humans.
The cover for issue 46 of Oncotarget features Figure 6, "Establishment of a SARS-CoV-2 pseudovirus that expresses SPIKE protein variants on the envelope of a lentiviral core, infection of human airway epithelial cells or lung cancer cells, and demonstration of MEKi attenuation of infectivity on primary human cells," published in "MEK inhibitors reduce cellular expression of ACE2, pERK, pRb while stimulating NK-mediated cytotoxicity and attenuating inflammatory cy
In a new study out of University of California San Diego School of Medicine, researchers have identified a universal strain of bacteria derived from healthy human skin that can treat the most common type of eczema, also known as atopic dermatitis.
